[ceph-users] problem on async+dpdk with ceph13.2.0

[冷镇宇]

Hello,

 

I’m trying to find a way to use async+dpdk as network on cep13.2.0. .After I 
have compiled ceph with dpdk and mount hugepage, I got a segmentation fault 
like this:




 ./bin/ceph-mon -i a -c ceph.conf

EAL:Detected 48 lcore(s)

EAL: No free hugepages reported in hugepages-1048576KB

EAL: Probing VFIO support...

EAL:PCI device :03:00.0 on NUMA socket -1

EAL: probe driver: 8086:1521 net_e1000_igb

 Caught signal (Segmentation fault) **

  in thread 7fbb45511700 thread_name:lcore-slave-1




my kernel version is CentOS 3.10.0-862.11.6, and dpdk version is 17.11, the 
ceph.conf is like this:




ms_cluster_type = async+dpdk

ms_public_type = async+dpdk

public_addr = 10.10.2.24

cluster_addr = 10.10.2.24

ms_async_op_threads = 2

ms_dpdk_coremask = 0xF

ms_dpdk_hugepages = /mnt/huge

ms_dpdk_rx_buffer_count_per_core = 2048

ms_dpdk_memory_channel = 2

 

Any suggestions?___

[ceph-users] Question about librbd with qemu-kvm

[冷镇宇]

Hi all,

I am using librbd of Ceph10.2.0 with Qemu-kvm. When the virtual machine booted, 
I found that there is only one tp_librbd thread for one rbd image. Then the 
iops of 4KB read for one rbd image is only 20,000. I'm wondering if there are 
some configures for librbd in qemu which can add librbd threads for one rbd 
image. Can someone help me? Thank you very much.___
